Title: Method and device for the continuous manufacture of thin-walled tubes of any length desired
Inventor: WITZENMANN HERBERT
IPC: B23K9/035
Filed: 1967-12-13
Abstract: 1,217,507. Making longitudinally jointed tubes; welding by fusion. H. WITZENMANN. 13 Dec., 1967, No. 56629/67. Headings B3A and B3R. In the continuous manufacture of thin-walled tube by forwardly feeding strip as it is shaped into tubular form with butting longitudinal edges, external clamping means travel with and feed the tube and hold it before, during and after welding until the welded seam has cooled. Strip 2, Fig. 1, from a reel 1 is drawn over a shaping tool 3 by pairs of clamping jaws 5 carried and traversed by driven endless conveyers 6. Cam guides 7 adjustable by screws 17 engage rollers on the jaws 5 to bring the jaws together. Alternatively, springs strips 7a adjusted by fluid pressure or electromagnetic devices 16 may be used to guide the jaws 5. The jaws 5 may be resilient or provided with resilient pads. The jaws 5 may have vacuum suction apertures to hold the tube in contact with the jaws. In a modification, Fig. 17, the jaws are in the form of split spring sleeves 19 pressed around the tube by rollers 42 on the guides 7. Internal support for the tube may be provided in the form of spring clips 32, Fig. 11, which travel with the tube, inflatable supports or a fixed hollow cylinder 22, Fig. 2, through which air or shielding gas is blown to exit through holes in the wall of the cylinder 22. After welding, the tube is cut by a flying cutter 14. Internal support may be provided by one or more reciprocated cylinders which are inflated during the forward movement and deflated during the reverse movement. Alternatively, a series of hemi-cylinders may be sequentially inflated, fed forward under the weld, deflated, rotated 180 degrees to the lower part of the tube and retracted. Welding may be effected by two torches positioned in tandem and controlled to weld different portions of the seam. One or both of the torches may be movable axially of the tube.

Abstract: 1,206,174. Discharge tubes. SYLVANIA ELECTRIC PRODUCTS Inc. 14 Dec., 1967 [19 Dec., 1966], No. 56922/67. Heading H1D. A method of opening an evacuated electron tube having a glass envelope with a projecting seal 17, for example for replacing a defective electron gun assembly in a colour or monochrome cathode ray tube, comprises positioning the projecting seal 17 within a hermetic chamber 24, evacuating the chamber, opening the tube seal 17 to the ambient vacuum of the chamber and admitting an inert atmosphere into the chamber and tube as a gaseous fill to prevent contaminants getting into the open envelope. As shown the neck of a cathode ray tube is supported within the upper portion 25 of chamber 24 with seal 17 projecting into the lower portion of the chamber, the two parts of the chamber being connected by grooves 26 in shoulder 27 on which the neck of the tube rests. After evacuating the chamber 24, preferably to the same extent as the vacuum within the tube, the seal is opened, for example, by fluid operated piston 39 which is released by unscrewing the threaded shaft 45 attached to the piston from engagement with the wall 53; the piston then being impelled to break the seal by the pressure differential inside and outside the chamber 24. A retaining basket 59 in the lower portion of the chamber catches the pieces of the seal to prevent their being drawn into the tube. Slowly from a gas supply, the inert atmosphere is admitted, preferably into the upper portion 25 of the chamber against the neck of the tube to provide a baffle effect. The piston 39 may also be mechanically or solenoid operated.

Title: Improvements in or relating to cleaning devices
IPC: G01N35/10
Filed: 1968-12-04
Abstract: 1,213,421. Cleaning pipes. LINSON INSTRUMENT AB. 4 Dec., 1968 [6 Dec., 1967] No. 67644/68. Heading F2N. An arrangement for cleaning an elongated member of substantially uniform cross-section, e.g. the take off tube 19 of a transfer device 17 used in a liquid-sample analysis apparatus, comprises a collar 25 having a bore 26 therethrough and adapted to encircle an axial portion of the tube 19 in radially spaced relation to define, between the walls of the bore and the tube 19 an annular space 27, means for relatively displacing the collar 25 and the tube axially over a length of the tube to be cleaned, and a suction conduit 30 connected to the bore 26 between the ends thereof. Suction in the conduit 30 causes fluid to flow around the tube 19 through the annular space 27 and in to the conduit 30 to entrain any loosely adhering matter on the exterior of the tube 19. Two sample carriers 13, 14 are advanced step-by-step in synchronism, along a support surface 12 each carrier holding a series of sample tubes 15, 16 respectively. During each best period a post 23 descends to insert the tube 19 of a probe 18 into the sample tube 15 at the take-off position suction being applied to a tube 21 attached to the probe 18 to suck up a measured quantity of the sample. The post 23 is then raised and rotated to locate the tube 19 above a sample tube 16 the measured quantity of the sample in the probe 19, with a measured quantity of conditioning liquid supplied through the tube 21, being ejected into the tube 16, the conditioning liquid washing out the interior of the probe. The bore 27 communicates with a recess 31 which may be supplied with a wash-liquid 32 delivered through a passage 34 and a conduit 63. When the tube 19 is withdrawn from the sample tube 15 suction at the conduit 30 draws liquid 32 from the recess 31 and air through the lower end of the annular space 27 to carry off any sample residues adhering to the outer surface of the tube 19 through the suction conduit 29. If the wash liquid is supplied continuously the probe tube 19 is subjected to a similar treatment as it descends into a tube 15. Alternatively, the wash liquid may be supplied only during the upward movement of the probe, or, be entirely dispensed with so that air is drawn through the annular space during upward, and downward, movement of the probe.

Abstract: 1,273,163. Selective punching. HONEYWELL Inc. 28 Nov., 1969 [30 Dec., 1968], No. 58348/69. Heading B4B. A mechanical actuator for a selectable punch 7 comprises an interposer flexure member 32 mounted between a pair of guide members 33, 34 and arranged to be reciprocated in order to drive the punch, electromagnetic means 21, 22, 26, 27, 28 being provided for selectively actuating the flexure member for contact with either of the guide members. The guide members and flexure member are secured to a reciprocable member 9 having a slot 42 in which the punch is slidable. The interposer which is of a magnetic material is is normally held against the guide member 33 by means of a permanent magnet 11 having bars 15, 16 fitted with coils 21, 22 respectively; in this position of the interposer the punch moves freely in the slot so that the punch does not pierce the material e.g. a punch card. Upon a voltage being applied to the coils as a result of signal being fed to an amplifier 27 and circuit 26, 28, an electromagnetic force is set up on the coils in opposition to the force of the magnet 11 so that the interposer is held in contact with the guide member 34. The punch is thereby prevented from movement in the slot so that a hole is pierced in the card. Towards the end of the return stroke of the member 9 the circuit provides for the electromagnetic force to be reversed so that interposer is returned to its initial position. At the end of the stroke an electromagnetic force aiding the force of the permanent magnet is terminated so that the interposer is held by the permanent magnet only.
